It is unrealistic to find a teacher temporarily during the semester. I'm already a parent. As long as parents and school Qi Xin work together to educate their children and adapt to each teacher's style, it is still a treasure for their growth. If you engage in confrontation, not only the school but also your children will be injured in the end.
